AT830E

AT830E CNC is an heavy duty roll turning lathe suitable for grooving and redressing rolling rolls and cylinders. Machine is specifically designed for roll maintenance shop applications. The four guide ways are able to grant the necessary rigidity and stability for long cylinder machining. The SIEMENS 840 D control has full potential for demanding performance of this application. The dedicated interface makes machine operations easy and fast for machine high productivity.The main shaft bearing position very close to the faceplate (i.e. application point of radial stresses) in order to reduce the bending momentum with advantages in terms of stiffness. Large special bearings are another element that insures high performance of this component. Main gear diameter is close to the max. roll diameter to increase stiffness, decrease bending momentum and smooth high torque transmission. Guideways are ground on the heavy ribbed cast iron bed: to assure the necessary geometrical precision and a good sliding surface. No reported rail guides are used for our lathes.
